Argus, a free iOS app from Azumio, turns a user’s iPhone into a comprehensive fitness hub. The app incorporates many of the features of other fitness apps into one. Argus tracks daily activities throughout the day including any workouts, walking, eating, drinking, cycling, etc. Users can take pictures of their meals and easily log activities throughout the day. The iPhone’s accelerometer is used in multiple ways including tracking steps during walks and runs, as well as during yoga and sleep by sensing movement during sleep. Expended calories are calculated and displayed and users can set goals and track fitness progress over time. Users can also opt to link the app with Facebook to connect with friends and post fitness activities.
